Problems solved by technology

In the process of use, scissors cut due to the limited contact area between the blade of the scissors and the fiber, and the cutting process is time-consuming and laborious; in the industrial production process, cutting with a guillotine knife, because the fiber cluster is thicker, the upper fiber presses the lower fiber during the cutting process , causing the upper fibers of the cut fiber cluster to be shorter than the lower fibers

Embodiment 1

[0024] Embodiment one, see figure 1 , a fiber cutting device, comprising two shear bodies and a connector 1, characterized in that: the shear body includes a shear handle 2 and a shear joint part, the shear joint part is arc-shaped, and the inside of the shear joint part is provided with A plurality of scissors 3, the scissors 3 are provided with a cutting edge, the outer side of the scissor part is provided with a shaft hole, and the scissor handle 2 is arranged on the inner side of the scissors. When in use, the scissors 3 are inserted into the fiber tuft, and then the scissor handle 2 is pressed together to cut off the fiber tuft.

[0025] As a further improvement of the above solution, a support rod 4 is provided on the outside of the scissors, and a spring 5 is provided between the support rods 4 . The scissor handle 2 can be automatically restored to the state of preparation before cutting, which increases ease of use and saves operating time.

Abstract

The invention provides a fiber cut-off device. The fiber cut-off device comprises two shear bodies and a connecting piece. The fiber cut-off device is characterized in that each of the shear bodies comprises a shear handle and a shearing portion which is arc-shaped; a plurality of shearing teeth are arranged on the inner side of the shearing portion, cutting edges are arranged on the shearing teeth, a shaft hole is formed in the outer side of the shearing portion, and the shear handle is arranged on the inner side of the shearing portion. During use, the shearing teeth are inserted into a fiber cluster, and then the shear handle is pressed to perform a cut-off operation of the fiber cluster. By arranging the shearing teeth to increase the contact areas of the cutting edges of the cutting device and the fibers, the fibers are more time- and labor-saving to shear, and the sheared fiber clusters are closer in length.

Description

technical field [0001] The invention relates to a cutting device, in particular to a fiber cutting device. Background technique [0002] Fiber refers to a substance consisting of continuous or discontinuous filaments. In animals and plants, fibers play an important role in maintaining tissues. Fibers are widely used and can be woven into thin threads, thread ends and hemp ropes, and can also be woven into fiber layers when making paper or felt. They are also commonly used to make other materials and form composite materials with other materials. [0003] Fiber clusters often need to be cut during use to meet the needs of different working surfaces. The prior art adopts the method of cutting or scissors cutting. In the process of use, scissors cut due to the limited contact area between the blade of the scissors and the fiber, and the cutting process is time-consuming and laborious; in the industrial production process, cutting with a guillotine knife, because the fiber cl...
